NASA to Build a Quieter Supersonic Passenger Jet

This is an artist’s concept of a possible Low Boom Flight Demonstration Quiet Supersonic Transport (QueSST) X-plane design. The award of a preliminary design contract is the first step towards the possible return of supersonic passenger travel – but this time quieter and more affordable. NASA’s award of a contract for the preliminary design of a “low boom†flight demonstration ... Read More »

New Microfluidic Screening Device May Speed Up DNA Insertion in Bacteria

In search of the ideal bacteria for use in a microbial fuel cell, researchers from MIT have developed a new microfluid device to quickly sort and identify the various strains. This technology, which could lead to a carbon-neutral method of harvesting energy for the grid from wastewater, may also be useful to doctors in identifying deadly infections more quickly. Genetically ... Read More »

MIT Develops New Imaging System with Open-Ended Bundle of Optical Fibers

The fibers of a new “optical brush†are connected to an array of photosensors at one end and left to wave free at the other. A new imaging system developed at the MIT Media Lab uses an open-ended bundle of optical fibers — no lenses, protective housing needed. The fibers are connected to an array of photosensors at one end; ... Read More »

Scientists Complete Primary Mirror for NASA’s James Webb Space Telescope

Inside a massive clean room at NASA’s Goddard Space Flight Center in Greenbelt, Maryland the James Webb Space Telescope team used a robotic am to install the last of the telescope’s 18 mirrors onto the telescope structure. Engineers have installed the 18th and final primary mirror segment on what will be the biggest and most powerful space telescope ever launched. ... Read More »

New Energy-Friendly Chip Can Perform Powerful AI Tasks

Engineers from MIT have designed a new chip to implement neural networks. It is 10 times as efficient as a mobile GPU, so it could enable mobile devices to run powerful artificial-intelligence algorithms locally, rather than uploading data to the Internet for processing. In recent years, some of the most exciting advances in artificial intelligence have come courtesy of convolutional ... Read More »

Scientists Develop Graphene Composite to Simplify Ice Removal

Rice University scientists embedded graphene nanoribbon-infused epoxy in a section of helicopter blade to test its ability to remove ice through Joule heating. (Credit: Tour Group/Rice University) Researchers at Rice University have developed a thin coating of graphene nanoribbons in epoxy that has proven effective at melting ice on a helicopter blade. The coating by the Rice lab of chemist ... Read More »

Yale Engineers Devise Quantum Technology On A Chip

Engineers at the Yale School of Engineering and Applied Science have devised a process of nanofabrication to create a silicon chip that contains all the components needed for a quantum information processor. The potential benefits of quantum technology are huge. Theoretically, it can complete in seconds certain tasks – like simulations of complex chemical processes or searching through huge amounts ...

New Material Can Store Solar Energy During the Day and Release it Later as Heat

The layer-by-layer solar thermal fuel polymer film comprises three distinct layers (4 to 5 microns in thickness for each). Cross-linking after each layer enables building up films of tunable thickness. Engineers from MIT have developed a new material could harvest sunlight by day and release heat on demand hours or days later. Imagine if your clothing could, on demand, release ... Read More »

Two-Stage Process Makes Incandescent Bulbs More Efficient

A proof-of-concept device built by MIT researchers demonstrates the principle of a two-stage process to make incandescent bulbs more efficient. This device already achieves efficiency comparable to some compact fluorescent and LED bulbs. Using a two-stage process that captures heat loss and reflects it back to the filament to be re-absorbed and re-emitted as visible light, engineers from MIT have ... Read More »

New Technique for Developing Nanodevices at One-Hundredth the Current Cost

External row of seven emitters that are part of a 49-emitter array. The scalloping on the exterior of the emitters, due to the layer-by-layer manufacturing, is visible. Credit: Anthony Taylor and Luis F Velásquez-García Researchers from MIT have developed new techniques for building microelectromechanical systems at one-hundredth of the current cost. Microelectromechanical systems — or MEMS — were a $12 ... Read More »
